FREE-Valve’s Double Offset Butterfly Valves can be used for shut-off and throttling control. It can ensure sealing more reliable and achieve non-leakage because of the resilient-seated design. The butterfly valve can realize rotary under the condition of low torque by the resilient-seated design , which means a longer service life ,so as to cost-effective of choosing actuator.

Features
1. Reliable sealing, convenient operation, opening and closing fast.
2. The valve’s seat is available in metal ,PTFE and graphite PTFE , which makes the valve suitable for liquid or gas service with many applications
3. The resilient-seated design ensures minimal seat wear and double offset disc design provides excellent throttling capabilities ,it has characteristic of super long usage life, frictionless closure,high temperature etc.
4. Blowout proof shaft design and the application of self lubricated bearings.
5.Preventing the disc from closing under over/under travel by adjusting mechanical stopper.
